DETACHING HORSES FROM CARRIAGES.

Specification of Letters Patent No. 4,828. dated October 29, 1846.

To all whom, it may concern:

Be it known that I, H. C. WIATT, of Weldon, in the county of Halifax andState of North Carolina, have invented a new and useful improvement inswinglet-rees for carriages, &c., for detaching horses from vehicles,thereby preventing injury and damage incurred by the running away ofhorses, which I denominate the safety-swingletree, and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theaccompanying drawings, making a part of this specificationviz., Figures1 and 2, which are isometrical views.

I make my swingle-tree A (Figs. 1 and 2) of any suitable material, andof a cylindrical or other form adapted to the purpose, on'the top ofwhich near the ends, I insert two pins a a to which are fixed thetraces; the traces to be kept from jarring off, by springs 6 Z) confinedby bolts or screws to the under side of the swingle-tree. In the centerof the swingle-tree is fastened a catch B which receives a spring Csituated on the shaft bar D through a slit or opening 0 and is held inits position by a spring key (Z inserted in the slit or opening 9 of thespring C. On the swingle-tree are stays or collars a e fittingsufiiciently loose as to allow it to-turn easily in them; which arefirmly secured to the shaft bar by bolts on the top and side. The key isdrawn out when occasion requires, by the cord F which is carried upthrough the bottom, or any other convenient part of the carriage withinreach of the driver. i

If the horse, or horses should start; by pulling the cord, the key willbe. instantly withdrawn and the force exerted by means of the traces,will cause the swingle-tree to turn and incline the pins in a horizontaldirection, as in Fig. 2 which position of the pins allows the traces, tosllp off and free the horse from the carriage.

What I claim as new, and desire to secure by Letters Patent consists inThe combination of the swingle-tree, springs, catch'and key, arrangedand operated substantially in the manner herein described.
